Mixer device

Abstract

At the bottom of the tank there are provided supports (4), (5), while the under side of the mixer is provided with corresponding surfaces (6), (7) for receiving the supports. In order to prevent the reaction force from the propeller (2) from tilting the front end of the mixer upwards, at least one of the supports (5) is arranged at a level above the level of the propeller shaft.

What is claimed is: 
     
       1. Apparatus for an easily releasable mounting of a submersible mixer on a tank bottom comprising in combination: an electric motor having a frame and a propeller on a substantially horizontal driving shaft, the frame of said motor having a cone-formed shell which extends from the bottom of the motor adjacent the propeller end;   a rack being connected to the top of the frame of the motor, said rack extending downward near the end opposite of the propeller and having another cone-formed shell;   a cone-formed support being positioned on the tank bottom to engage corresponding surfaces in said cone-formed shell;   another cone-formed support being positioned on the tank bottom at a level higher than said cone-formed support and said shaft, said other cone-formed support to engage corresponding surfaces in said other cone-formed shell, thereby preventing the reaction force from the propeller to raise the front end of the mixer during operation; and   a wire being connected to each said cone-formed and other cone-formed supports to permit said mixer to be lowered and raised.
